ROBERT B. DULA, OF WENTZVILLE, MISSOURI.

FUNNEL FOR FILLING S ACKS OR BAGS.

SPECIFICATION forming part of Letters Patent No. 241,945, dated May 24, 1881.

Application filed February 4, 1881. (No model.)

T 0 all whom it may concern Be it known that I, R. B. DULA, of Wentzville, in the county of St. Charles and State of Missouri, have invented certain new and useful Improvements in Funnels for Packing Tobacco, &c.; and I do hereby declare that the following is afull, clear, and exact description oftheinvention,which willenableothersskilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a partof this specification.

My invention is an improvement in funnels which are used to facilitate the introduction of mill products into sacks or bags, and applicable especially in filling and packing smoking-tobacco into small bags.

It consists of a tube, cut away at its lower end on one side about one-half its length, provided with a flaring or funnel-shaped mouth, andan auxiliary rectangular piece adapted to fit over said tube, being hinged to it by suitable means, so that by moving said auxiliary; piece about its axis a reduction of the end offi said tube may be effected to easily receive the, mouth of a bag, which end may by a reverse" movement of said auxiliary piece be again enlarged to expand the mouth of the bag and hold it open to receive its measure.

In my drawings, Figure 1 is an elevation of my funnel. m Fig. 2 is a vertical section of said. funnel, showing the movement of the auxiliary piece. Fig. 3 is a plan or horizontal section of same.

' Similar reference-letters denote like parts in all of the figures.

Referring to drawings, A is a tube cut away on one side between points a b obliquely. Said tube is rectangular in general form, preferably, and provided at the top with afiaring mouth, B, splayed on all four sides to receive, without liability to overflow, the product to be bagged.

O is an auxiliary piece having a general shape conforming to that of the tube, and adapted to fit snugly thereon. This piece is hinged at points 0 by rivets d d, which pass through the two pieces of metal on each side, holding them together independently.

D is a bag held in place upon the end of the funnel, ready to receive its measure.

In the use of my funnel its operation, which is simple, is as follows: With one hand I clasp the lower end of tube A, and at the same time the auxiliary piece 0, and draw them together to reduce the size of the funnels end. I now place the bag on said end loosely. YVith one hand againl clasp the upper end of the tube and at the same time the upper end of the auxiliary piece 0, and draw them together to bring the lower end of the funnel to its normal size to expand the mouth of bag and hold it open while it is being filled. A clasp, 6, formed of wire and secured in a loop,f, is now brought down over the upper end of the auxiliary piece to hold it in place while the bag is being filled and the tobacco rammed.

In my drawings I show the tube of my funnel rectangular in sectional form; but it is obvious that the same construction and arrangement might be applied to other forms-say, for instance, oval or circular. The form shown, however, I prefer, as it is believed to be most convenient for the purpose.

The auxiliary piece I prefer to have hinged, as described, though I do not wish to be confined to this particular manner, as other suitable methods may be used in this connection, possibly to advantage in some cases. As, for instance, a rod passing entirely through the tube and hammered down on both sides might be substituted.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. Afunnel composed of tube A and flaring mouth B, the former having its sides parallel to its longitudinal axis, and cut away obliquely a part of its length on one side, in combination with a conformed auxiliary piece pivoted or hinged thereto and snugly fitted thereon, adapted to receive a bag the whole or a greater part of its length, as and for the purpose specified.

2. A funnel composed of a tube and a flaring mouth, the former having its sides parallel to its longitudinal axis, and cut away obliquely a part of its length on one side, in combination with a conformed auxiliary piece piv otetl 0r hinged thereto and fitted thereon, said my own I afh'x my signature in presence of two tube and auxiliary piece being adapted to rewitnesses. ceive a bag the whole or a greater part of its ROBERT E. DULA. length, and the hinged link efor securing said Witnesses: auxiliary piece in place, substantially as and JOEL CARR, for the purpose set forth. DEHAVEN R. SMITH.

In testimony that I claim the foregoing as
